📋 Description

• Backend API Development (50-60%): During key infrastructure sprints, you will focus heavily on building, scaling, and maintaining the Python or Go services. • iOS Core Development (40-50%): Design and maintain complex iOS applications and frameworks using Swift and Objective-C. • System-Level Engineering: Deep dive into iOS internals (processes, security, and automation frameworks) to support custom hardware or software integrations. • Backend Integration: Develop, test, and maintain robust, scalable APIs in Python (FastAPI/Flask) or Go to support mobile features and data synchronization. • Ecosystem Troubleshooting: Provide high-level technical support for the entire Apple stack, including code-signing, provisioning, MDM (Mobile Device Management), and CI/CD pipelines. • Collaboration: Work closely with infrastructure teams to ensure mobile devices are correctly isolated and containerized within our broader service environment.

🎯 Requirements

• Minimum 4 years of software development experience in IOS development and backend technologies. • The iOS Power User Expertise in Swift and a strong working knowledge of Objective-C. • Deep understanding of iOS Internals: Process management, keychain, background tasks, and system performance tuning. • Experience with XCUITest and mobile automation tools (e.g., Maestro, Appium, or custom XCTest runners). • Mastery of the Apple Deployment cycle: Certificates, Provisioning Profiles, App Store Connect, and TestFlight. • Proficiency in either Python or Go. • Experience designing RESTful or gRPC APIs. • Knowledge of Docker and containerization strategies for isolating service environments. • Understanding of networking protocols (WebSockets, HTTP/2, SSH tunneling). • Good understanding of Design patterns and Data Structures and Algorithms.

🏖️ Benefits

• Support-Oriented: Willingness to provide "on-call" or deep-dive technical support when Apple ecosystem updates break existing workflows. • Architecture First: Ability to write Architecture Decision Records (ADRs) to justify tech stack choices. • Security-Conscious: An instinctive understanding of why we isolate device-manipulation scripts in Docker for security.
